Marieke Flament utilized her London Business School network during launch sequence

When Marieke Flament got offered a spot inside Goldman Sachs-backed Circle, which lets people instantly send payments— and GIFs and emojis — in a message via bitcoin’s blockchain, she wasn’t sold. But after wrapping her head around the technology’s illustrious potential, she launched the US company’s European business in April this year.

“I thought: Oh my God. This is huge. This is going to be like the Internet,” Marieke says.

She adds: “The blockchain will disrupt many more things than we can envision today — smart contracts, the IoT, and probably how you hold your identity…. This is blockchain 1.0. We're yet to see 2.0 and 3.0.”

The EU roll-out has been made easier by Marieke’s London Business School network. The MBA grad tapped into its rich talent pool; she regularly plays basketball with a group of LBS alums. “That network is hugely valuable,” says Circle’s managing director for Europe. “I have people who work at Google, Amazon — the best breed of superstar companies — and entrepreneurs.”

The UK’s vote to exit the EU, however, looms like the spectre at the feast. Circle uses its UK base to “passport” its services across European borders — but Brexit has thrown that agreement into doubt.

Marieke admits Circle fears for its future in the UK: “If we can’t passport anymore it means we have to go into another EEA [European Economic Area] country and renew the passport from there,” she says, compounding fears that UK fintech could falter outside of the EU.

If that’s keeping Marieke awake at night, investors don’t seem to have the jitters. Last month, Circle raised $60 million in equity funding from backers including Chinese tech giant Baidu — part of the cash is earmarked for expansion into China. That takes Circle’s total funding to $136 million.

Circle’s value proposition is simple, despite the complexities of cryptocurrencies: It wants cross-border payments to be as simple as domestic payments; like chatting with someone over Skype. “We want money to work like the Internet does,” Marieke says.

A clear challenge, however, is that consumers and banks have doubts over blockchain’s permissionless structure — and bitcoin’s reputation is less than rosy.

Blockchain is essentially a public, digital ledger of transactions that emerged with bitcoin. It uses cryptography, allowing participants to securely manipulate the ledger without a central authority.

Since foundation in 2013, Boston-based Circle has moved away from its roots in bitcoin to connect consumers using dollars, pounds, euros and renminbi.

Marieke says: “We want to use the blockchain as a rail. No end consumer will ever want to hold bitcoins unless they’re really into it and understand the technology.”

That’s thrown Circle into competition with older money transfer businesses, such as PayPal-owned Venmo and TransferWise. Rebutting my suggestion that there’s much ground to make up, Marieke says Circle’s use of technologies like blockchain and machine learning, which can help manage risk and combat fraud, makes it unique: “It enables us to be faster and more nimble,” she says.

It’s exactly the kind of challenge that lured Marieke away from a senior post as VP for EMEA at Hotels.com, the accommodation booking site. “I’ve always wanted to join a start-up,” she says. “And Circle is just that. It has amazing founders. And it’s well-backed, with a fantastic vision that is extremely disruptive. You have a once in a lifetime chance to join a business like that.”

Bitcoins and artificial intelligence are a long way from her roots at Boston Consulting Group, a firm she joined in Paris after business school in 2011. But even for MBAs with traditional career paths, Marieke reckons there are links to fintech.

“Consulting taught me how to get quickly into an industry and to ask the right questions,” she says, adding: “Fintech is about data. You learn that [analytical] skill-set in a consulting environment.”
